 The loan is repayable according to the mechanism agreed upon with the bank. If you fail to repay the debt, you must contact the bank and ask them for one of the following things that you find suitable for your situation:
1) Submit a request for a settlement of the loan repayment 

2) Submit a rescheduling request

3) Submit a request to transfer the loan to another bank
